Abstract
The utility model discloses a cylindrical shank connector of a modular boring cutter, and belongs to the technical field of metal processing cutting. The cylindrical shank connector solves the problem of improving connection accuracy of a hole shaft of the boring cutter. The cylindrical shank connector is characterized in that a stopping pin is arranged in the direction of the diameter of a protrusion end of a cylinder, and two ends of the stopping pin are exposed externally; a stopping pin groove is formed in the inner wall of an inwardly-concave cavity body at the concave end of the cylinder, and the size of the stopping pin groove is matched with that of the two externally-exposed ends of the stopping pin; and the protrusion end of the cylinder is in transmission connection with the inwardly-concave cavity body through torsion of the stopping pin. A taper hole is formed in the hole wall of the inwardly-concave cavity body. A taper hole end portion is arranged on the side face of the protrusion end of the cylinder and is in a taper shape. A taper end tightly-jacking screw is arranged in the taper hole. The end portion of the taper end tightly-jacking screw is in interference fit with the taper hole end portion. The protrusion end of the cylinder and the inwardly-concave cavity body are fastened, connected and locked through the taper end tightly-jacking screw. The cylindrical shank connector of the modular boring cutter has the advantages that cutter bars which are in modular connection can have largest rigidity and coaxality, and repeated installation accuracy of the boring cutter is improved. Free combination of modules can be achieved according to different machining requirements, high-quality machining is achieved, and use is flexible and convenient.
Description
Technical field
The utility model relates to a kind of cylindrical handle interface of modular boring cutter, belongs to metal machining cutting tool technical field.
Background technology
Along with the continuous development of Computerized Numerical Control processing technology, the integral type boring cutter can not be satisfied the demand, the substitute is modular boring cutter miscellaneous.The modular boring cutter namely is that boring cutter is divided into: a plurality of parts such as basic handle, extension bar, undergauge bar, boring cutter body, then according to concrete processing content (heavy boring, right boring; The diameter in hole, the degree of depth etc.) carry out independent assortment.So not only reduce the quantity of handle of a knife widely, reduced cost, also corresponding various processing request rapidly, and prolong the life-span of cutter integral body.
Though the modular boring cutter is compared with the integral type boring cutter and is had many advantages, but its each several part need connect by interface, at present the connected mode that generally adopts is the hole axle mode that is connected: side-strengthened connects, only be to have reached fixing purpose, not only the end face of connector can not closely contact, poor rigidity, radial position also can change when compressing, and it is low to connect precision; The end face contact connects, and end face can reach tight contact, and rigidity increases, but because be matched in clearance between the axle of hole, it is not high equally to connect precision.Therefore the hole axle is connected and can has the gap all the time between the hole of mode and the axle, and connecting precision cannot guarantee, can not satisfy the processing needs of modular boring cutter.
Summary of the invention
The purpose of this utility model is: a kind of cylindrical handle interface of modular boring cutter is provided, can reaches high connection precision, high rigidity, high repetition installation accuracy simultaneously.
For achieving the above object, the technical scheme of taking is: a kind of cylindrical handle interface of modular boring cutter, comprise coaxial cylindrical nose and the recessed end of cylinder mutually, and it is characterized in that: described cylindrical nose diametric(al) is equipped with backing pin, and expose at two ends; The concave cavity inwall of the recessed end of described cylinder is equipped with the backing pin groove, and its size is complementary with the two ends that described backing pin exposes; Described cylindrical nose places in the described concave cavity, and the backing pin groove that the two ends of described backing pin and concave cavity inwall are equipped with joins, and described cylindrical nose is connected by described backing pin torque transmission with described concave cavity.
Described concave cavity hole wall is equipped with taper hole, and cylindrical nose side is equipped with the taper hole end, and is tapered; The built-in awl end of described taper hole presses closer screw, and described awl end presses closer screw end and described taper hole end interference fit, presses closer screw by described awl end between described cylindrical nose and the described concave cavity and is fastenedly connected locking.
The utility model has the advantages that: interface adopts cylinder to cooperate and taper hole interference fit connected mode, guaranteeing to connect concentricity precision contacts fully with end face, can satisfy high connection precision simultaneously and be connected rigidity, guarantee that the knife bar that modular connects has maximum rigidity and alignment, and improved the repetition installation accuracy of boring cutter.In the boring process, no matter modular boring cutter cylindrical handle interface is used as heavy boring cutter interface still as the interface of fine boring cutter, all can realize the module independent assortment according to different processing requests, accomplishes high-quality processing, uses flexible, convenient.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the cylindrical handle interface decomposition texture schematic diagram of modular boring cutter;
Fig. 2 interconnects the joint portion cross-sectional view for the cylindrical handle interface of modular boring cutter.
Among the figure, the recessed end of 1-cylinder; 2-concave cavity; 3-awl end presses closer screw; 4-taper hole; 5-backing pin groove; 6-backing pin; 7-taper hole end; 8-cylindrical nose.
The specific embodiment
The cylindrical handle interface decomposition texture of modular boring cutter is shown in Fig. 1, and the recessed end 1 of cylinder and cylindrical nose 8 interconnect the joint portion cross-section structure and be shown in Fig. 2.As depicted in figs. 1 and 2, a kind of cylindrical handle interface of modular boring cutter comprises coaxial cylindrical nose 8 and the recessed end 1 of cylinder mutually, and it is characterized in that: described cylindrical nose 8 diametric(al)s are equipped with backing pin 6, and expose at two ends; Concave cavity 2 inwalls of the recessed end 1 of described cylinder are equipped with backing pin groove 5, and its size is complementary with the two ends that described backing pin 6 exposes; Described cylindrical nose 8 places in the described concave cavity 2, and the backing pin groove 5 that the two ends of described backing pin 6 and concave cavity 2 inwalls are equipped with joins, and described cylindrical nose 8 is connected by described backing pin 6 torque transmission with described concave cavity 2.
Described concave cavity 2 hole walls are equipped with taper hole 4, and cylindrical nose 8 sides are equipped with taper hole end 7, and are tapered; Described cooperation taper hole 4 built-in awl ends press closer screw 3, and described awl end presses closer screw 3 ends and described taper hole end 7 interference fit, press closer screw 3 by described awl end between described cylindrical nose 8 and the described concave cavity 2 and are fastenedly connected locking.
Be connected (see figure 2) under the locking state at cylindrical nose 8 with recessed end concave cavity 2 assemblings, described cylindrical nose 8 places in the recessed end concave cavity 2, and described backing pin 6 places in the backing pin groove 5; Described awl end presses closer screw 3 and screws in the taper hole 4, because described awl end presses closer screw 3 ends and taper hole end, cylindrical nose 8 side 7 surperficial interference fit, makes cylinder nose 8 and recessed end concave cavity 2 both ends of the surface fit tightly; Described cylindrical nose 8 surperficial backing pins 6 place in the backing pin groove 5 of recessed end 1 concave cavity 2 of cylinder, can bear very large cutting torsion in thick, the fine finishining process.
